Value proposition

Character-Driven Behavior OS that combines IP characters, AI, and lifestyle data to drive sustained behavior change in sleep, health, beauty, learning, and finance — solving the 'knowing vs. doing' gap through emotional engagement rather than willpower.

Products and solutions

Charamix (キャラミクス) — Character-Driven Behavior OS platform featuring: character-driven engagement, ID federation, lifestyle data integration, personalized AI recommendations. Offered as standalone app and SDK/API for third-party integration. Sleep-first vertical with planned expansion into beauty, finance, e-commerce, education, and wellness.

Unique value

Combines IP character expertise (proven hit track record) with controlled LLM technology that preserves IP/worldview integrity (not free-form LLM chat), emotional design (intrinsic motivation), incentive design (extrinsic motivation), and contextual AI personalization — creating a repeatable behavior change system that traditional health apps cannot achieve.

Target customer

B2B: Enterprises in beauty, retail, finance, telecom, wellness, and education sectors; B2G: Local municipalities for citizen health/wellbeing programs; B2C: End users via Charamix app and SDK/API integrations into partner services.

Industries served

Sleep/Health, Beauty, Retail, Finance, E-commerce, Wellness, Education, Local Government (municipal health programs)

Technology advantage

Controlled LLM architecture that protects IP and character worldviews (unlike open-ended chatbots); proprietary emotional design + incentive design framework built on 10+ years of hit IP production experience; SDK/API-first architecture enabling cross-industry deployment; sleep-first data moat creating a unique behavioral data asset.

How they differentiate

Unlike Pictoria (AI VTuber/operator focus) or Character.AI (open-ended chat), Rimoa focuses specifically on behavior change through controlled character interactions with IP-safe LLM, emotional design, and lifestyle data integration — positioning as a 'Behavior OS' rather than a chat interface. Deep sleep-first vertical focus with cross-industry SDK/API expansion strategy.
